"One day at Miles's apartment, he wrote on some manuscript paper the symbols for G-minor and A-augmented. And he said, 'What would you do with that?' I didn't really know, but I went home and wrote 'Blue in Green.'"

- Bill Evans

The four bar opening was then apparently used by Evans as the intro to "Alone Together" on a Chet Baker session on Dec. 30, 1958.
